Concassé means roughly chopped, usually applied to tomatoes. Pour boiling water over very firm, ripe tomatoes, leave for 10 seconds, then pour off the water. Peel off the skin, cut in half, remove the seeds with a teaspoon or melon-baller, cut in quarters and chop into 7mm or 3mm dice. Concassé may be added to a sauce or used as a garnish.
